title: Herlyn Werner Wunderlich syndrome: an unusual presentation of acute vaginal pain.
abstract: BACKGROUND
  Herlyn Werner Wunderlich Syndrome (HWWS) is a congenital abnormality of the Müllerian duct system resulting in uterovaginal duplication, obstructive hemivagina, and ipsilateral renal agenesis. It typically presents shortly after menarche with gradual onset of progressive pelvic pain.
  
  
  METHODS
  We report a case of a 19-year-old female who presented to the Emergency Department with sudden onset of severe vaginal pain that was determined to be due to hematocolpos; imaging confirmed the diagnosis of HWWS.
  
  
  CONCLUSIONS
  To the best of our knowledge abrupt onset of vaginal pain due to HWWS has not been reported previously. We present this case to increase awareness among emergency physicians of this rare and interesting entity.
